This application claims benefit of priority to U.S. Provisional Application No. 62/883,548, filed Aug. 6, 2019, titled “Camera with Bumper for Cushioning Lateral Movement”, which is hereby incorporated by reference in its entirety.

BACKGROUND Technical Field

This disclosure relates generally to architecture for a camera having one or more bumpers to cushion lateral movement of a moveable platform as it approaches a stationary structure.

Description of the Related Art

The advent of small, mobile multipurpose devices such as smartphones and tablet or pad devices has resulted in a need for high-resolution, small form factor cameras for integration in the devices. Some small form factor cameras may incorporate optical image stabilization (OIS) mechanisms that may sense and react to external excitation/disturbance by adjusting location of the optical lens on the X and/or Y axis in an attempt to compensate for unwanted motion of the lens. Some small form factor cameras may incorporate an autofocus (AF) mechanism whereby the object focal distance can be adjusted to focus an object plane in front of the camera at an image plane to be captured by the image sensor. In some such autofocus mechanisms, the optical lens is moved as a single rigid body along the optical axis of the camera to refocus the camera.

This specification includes references to “one embodiment” or “an embodiment.” The appearances of the phrases “in one embodiment” or “in an embodiment” do not necessarily refer to the same embodiment. Particular features, structures, or characteristics may be combined in any suitable manner consistent with this disclosure.

“Comprising.” This term is open-ended. As used in the appended claims, this term does not foreclose additional structure or steps. Consider a claim that recites: “An apparatus comprising one or more processor units . . . ” Such a claim does not foreclose the apparatus from including additional components (e.g., a network interface unit, graphics circuitry, etc.).

“Configured To.” Various units, circuits, or other components may be described or claimed as “configured to” perform a task or tasks. In such contexts, “configured to” is used to connote structure by indicating that the units/circuits/components include structure (e.g., circuitry) that performs those task or tasks during operation. As such, the unit/circuit/component can be said to be configured to perform the task even when the specified unit/circuit/component is not currently operational (e.g., is not on). The units/circuits/components used with the “configured to” language include hardware—for example, circuits, memory storing program instructions executable to implement the operation, etc. Reciting that a unit/circuit/component is “configured to” perform one or more tasks is expressly intended not to invoke 35 U.S.C. § 112, sixth paragraph, for that unit/circuit/component. Additionally, “configured to” can include generic structure (e.g., generic circuitry) that is manipulated by software and/or firmware (e.g., an FPGA or a general-purpose processor executing software) to operate in manner that is capable of performing the task(s) at issue. “Configure to” may also include adapting a manufacturing process (e.g., a semiconductor fabrication facility) to fabricate devices (e.g., integrated circuits) that are adapted to implement or perform one or more tasks.

“First,” “Second,” etc. As used herein, these terms are used as labels for nouns that they precede, and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). For example, a buffer circuit may be described herein as performing write operations for “first” and “second” values. The terms “first” and “second” do not necessarily imply that the first value must be written before the second value.

“Based On.” As used herein, this term is used to describe one or more factors that affect a determination. This term does not foreclose additional factors that may affect a determination. That is, a determination may be solely based on those factors or based, at least in part, on those factors. Consider the phrase “determine A based on B.” While in this case, B is a factor that affects the determination of A, such a phrase does not foreclose the determination of A from also being based on C. In other instances, A may be determined based solely on B.

It will also be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the intended scope. The first contact and the second contact are both contacts, but they are not the same contact.

The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

As used herein, the term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

DETAILED DESCRIPTION

Some embodiments include camera equipment outfitted with one or more bumper features that may be used to cushion lateral movement of a moveable platform of the camera. In some examples, the bumper(s) may be used to cushion lateral movement of the moveable platform before the moveable platform reaches a lateral end stop defined by a stationary structure of the camera. Additionally, or alternatively, the bumper(s) may cushion lateral movement of the moveable platform as the moveable platform approaches the stationary structure. The bumper(s) may prevent an undesirable collision between the moveable platform and the stationary structure (e.g., as a result of a drop event) that may damage the camera, negatively impact camera performance, and/or negatively impact user experience. In some instances, an undesirable “clicking” sound may be produced if the moveable platform collides with the stationary structure. The bumper(s) may provide acoustic mitigation to prevent or lessen such unwanted acoustics. Furthermore, in some examples, the bumper(s) may be used to reduce or limit an amount of electrostatic charge accumulation on the moveable platform and/or the stationary structure.

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it will be apparent to one of ordinary skill in the art that some embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

FIGS. 1A-1G illustrate views of an example camera 100 having an example bumper arrangement for cushioning lateral movement of a moveable platform of the camera. FIG. 1A shows a perspective view of the camera 100 and a detail view of component(s) of the bumper arrangement. FIG. 1B shows a perspective view of component(s) of the bumper arrangement. FIG. 1C shows a cross-sectional view of the camera 100. FIG. 1D shows a detail view of a portion of the camera, as indicated by detail circle 1D shown in FIG. 1C. FIG. 1E shows another cross-sectional view of the camera 100. FIG. 1F shows a detail view of a portion of the camera 100, as indicated by detail circle 1F shown in FIG. 1E. FIG. 1G shows another perspective view and detail views of the bumper arrangement.

In some embodiments, the camera 100 may include a lens group 102, an image sensor 104 (see FIG. 1C), an actuator 106, a stationary structure 108, and/or a moveable platform 110. The lens group 102 may include one or more lens elements that define an optical axis 112. The image sensor 104 may capture light that passes through the lens group 102. The actuator 106 may be configured to move the lens group 102 relative to the image sensor 106.

According to various embodiments, the stationary structure 108 may include a shield can that covers at least a portion of the internal component(s) of the camera 100. Furthermore, the moveable platform 110 may include a magnet holder that holds one or more magnets of the actuator 106. In other embodiments, the stationary structure 108 may include one or more components other than the shield can, and the moveable platform 110 may include one or more components other than the magnet holder.

In some embodiments, the moveable platform 110 may be coupled to the lens group 102. For instance, the moveable platform 110 may be coupled to the lens group 102 such that the moveable platform 110 moves together (e.g., in lockstep) with the lens group 102, e.g., when the actuator 106 moves the lens group 102 relative to the image sensor 104. In some examples, the moveable platform 110 may be coupled to the lens group 102 such that the moveable platform 110 and the lens group 102 are moveable together in one or more directions orthogonal to the optical axis 112. In some embodiments, the moveable platform 110 may include an outer surface portion 114. Furthermore, the stationary structure 108 may include an inner surface portion 116. In some examples, the outer surface portion 114 and the inner surface portion 116 may face each other. According to various embodiments, the inner surface portion 116 of the stationary structure 108 may define a lateral end stop with respect to lateral movement of the moveable platform 110, e.g., movement in one or more directions orthogonal to the optical axis 112. The lateral end stop, for example, may stop the moveable platform 110 from moving in a direction orthogonal to the optical axis 112 (e.g., movement resulting from impact in a drop event) beyond the inner surface portion 116 of the stationary structure 108.

In some embodiments, the camera 100 may include a suspension spring structure that couples the moveable platform 110 with the lens group 102. The suspension spring structure may be used to guide movement of the lens group 102 along the optical axis 112 and/or in one or more directions orthogonal to the optical axis 112 in a controlled manner. For example, the suspension spring structure may include a top spring 118 and/or a bottom spring 120. According to some embodiments, the suspension spring structure may couple the moveable platform 110 with a lens carrier 122 that is configured to hold or otherwise support the lens group 102. In some examples, the lens group 102 may be fixedly attached to the lens carrier 122. The suspension arrangement may couple the lens carrier 122 with the moveable platform 110 such that the lens carrier 122 and the moveable platform 110 are moveable together, relative to the image sensor 104, in one or more directions orthogonal to the optical axis 112. Additionally, or alternatively, the suspension arrangement may couple the lens carrier 122 with the moveable platform 110 such that the lens carrier 122 (and the lens 102) are moveable, relative to the moveable platform 110 and/or the image sensor 104, along the optical axis 112. In various embodiments, the stationary structure 108 may be stationary relative to movement of the moveable platform 110 and/or the lens carrier 122.

In some examples, the actuator 106 may be a voice coil motor (VCM) actuator that includes one or more coils and one or more magnets. In some embodiments, the actuator 106 may include magnet(s) 124 and autofocus (AF) coil(s) 126 that are configured to magnetically interact to move the lens group 102 along the optical axis 112, e.g., to provide AF movement of an image captured via the image sensor 104. Additionally, or alternatively, the actuator 106 may include magnet(s) 124 and optical image stabilization (OIS) coils 128, e.g., to provide OIS movement of an image captured via the image sensor 104.

According to various embodiments, the camera 100 may include a bumper arrangement for cushioning lateral movement of the moveable platform 110, e.g., as the moveable platform 110 approaches the stationary structure 108. In some embodiments, the bumper arrangement may include one or more spring bumpers 130, a protrusion 132, and/or a recess 134. The spring bumper 130 may be attached to an outer surface (e.g., the outer surface portion 114) of the moveable platform 110. The protrusion 132 may extend from the stationary structure 108 towards the spring bumper 130. In some embodiments, the protrusion 132 may engage (e.g., make contact with) the spring bumper 130 when a lateral movement stroke of the moveable platform 110 reaches a stroke threshold. The protrusion 132 may be defined by the stationary structure 108 in some embodiments. The recess 134 may be defined by the moveable platform 110. Furthermore, the recess 134 may be formed to receive a deflected portion of the spring bumper 130 when the lateral movement stroke of the moveable platform 110 exceeds the stroke threshold, e.g., as indicated in FIGS. 1D and 1F. For example, the recess 134 may be sized and/or shaped such that it provides a space within which at least a portion of the spring bumper 130 may extend during deflection.

As indicated in FIG. 1B, the spring bumper 130 may be attached to a side of the moveable platform 110. While FIGS. 1A-1G show a spring bumper 130 to one side of the moveable platform 110, the bumper arrangement may include one or more additional spring bumpers 130 (and/or one or more other corresponding bumper arrangement components, such as protrusion(s) 132 and/or the recess(es) 134) attached to one or more additional sides of the moveable platform 110. For example, the moveable platform 110 may have a first side 136 a, a second side 136 b, a third side 136 c, and a fourth side 136 d. The third side 136 c may be opposite the first side 136 a. The fourth side 136 d may be opposite the second side 136 b. In some embodiments, the spring bumper 130 may be attached to the first side 136 a. Additionally, or alternatively, one or more spring bumpers 130 may be attached to the second side 136 b, the third side 136 c, and/or the fourth side 136 d. In some embodiments, the spring bumper 130 may be a single component that is attached to and/or encircles multiple sides of the moveable platform 110, such that bumper elements are included at those sides. In a non-limiting example, the spring bumper 130 may comprise a component formed of a sheet of metal, and the component may encircle the first side 136 a, the second side 136 b, the third side 136 c, and/or the fourth side 136 d.

In some embodiments, the spring bumper 130 may be formed of a sheet of metal. The spring bumper 130 may include one or more bumper elements 138 configured to engage with the protrusion(s) 132, e.g., when a lateral movement stroke of the moveable platform 110 satisfies a stroke threshold. Furthermore, the bumper element(s) 138 may be deflected by the protrusion(s) 132 and into the recess(es) 134, e.g., when the lateral movement stroke of the moveable platform 110 exceeds the stroke threshold. For example, FIGS. 1D and 1F provide examples of a bumper element 138 in a deflected state 138′. The bumper element(s) 138 may be X-shaped in some embodiments, e.g., as indicated in FIGS. 1B and 1G. However, the bumper element(s) 138 may be any other suitable shape in various embodiments. As a non-limiting example, the bumper element(s) 138 may be tear-drop-shaped in some embodiments. A spring bumper 130 may include any number of bumper element(s) 138 at each of one or more sides of the moveable platform 110. For example, the spring bumper 130 may include a first bumper element 138 a and a second bumper element 138 b at the first side 136 a of the moveable platform 110. The first bumper element 138 a and the second bumper element 138 b may be formed from a single component (e.g., by etching, laser ablating, punching, and/or otherwise removing material from a same sheet of metal). According to various examples, the spring bumper 130 may be attached to the moveable platform 110 via an adhesive 140, e.g., as indicated in FIG. 1G.

According to some embodiments, the spring bumper 130 and the shield can 108 may be made of one or more materials that provide a reduction in triboelectric static charge buildup that occurs due to contact between the spring bumper 130 and the shield can 108. For example, the spring bumper 130 and the shield can 108 may each be formed of metal, which may allow for a reduction in triboelectric static charge buildup as compared to, e.g., a metal component that comes into contact with a plastic component. In some instances, triboelectric static charge buildup may negatively impact performance of the camera 100 and/or user experience with the camera 100. For example, triboelectric static charge buildup may lead to jump step issues after certain events (e.g., drop events).

FIGS. 2A-2C illustrate views of another example bumper arrangement 200 for cushioning lateral movement of a moveable platform of a camera. FIG. 2A shows a side view of the bumper arrangement 200. FIG. 2B shows a cross-sectional view of the bumper arrangement 200. FIG. 2C shows another cross-sectional view of the bumper arrangement 200.

In some embodiments, the camera may be similar in some respects to the camera 100 described above with reference to FIGS. 1A-1G. For example, the camera may include a lens group (e.g., lens 102 in FIG. 1A), a lens carrier (e.g., lens carrier 122 in FIG. 1A), an image sensor (e.g., image sensor 104 in FIG. 1C), an actuator (e.g., actuator 106 in FIG. 1A), a moveable platform 202, and/or a stationary structure 204 (see FIGS. 2B-2C). The lens group may include one or more lens elements that define an optical axis. The image sensor may capture light that passes through the lens group. The actuator may be configured to move the lens group relative to the image sensor. Furthermore, the camera may include a suspension spring structure, such as the suspension spring structure described above with reference to FIGS. 1A-1G.

According to some embodiments, the stationary structure 204 may include a shield can that covers at least a portion of the internal component(s) of the camera. Furthermore, the moveable platform 202 may include a magnet holder that holds one or more magnets 206 of the actuator. In other embodiments, the stationary structure 204 may include one or more components other than the shield can, and the moveable platform 202 may include one or more components other than the magnet holder.

In some embodiments, the moveable platform 202 may be coupled to the lens group. For instance, the moveable platform 202 may be coupled to the lens group such that the moveable platform 202 moves together (e.g., in lockstep) with the lens group, e.g., when the actuator moves the lens group relative to the image sensor. In some examples, the moveable platform 202 may be coupled to the lens group such that the moveable platform 202 and the lens group are moveable together in one or more directions orthogonal to the optical axis. In various embodiments, the moveable platform 202 may have multiple sides, e.g., four sides like the moveable platform 110 shown in FIG. 1B. The moveable platform 202 may encircle the lens carrier and/or the lens group in some embodiments. The moveable platform 202 may have fewer or more than four sides in some embodiments.

According to various embodiments, the bumper arrangement 200 may include one or more tabs 208 that protrude from the moveable platform 202, such that the tab(s) 208 extend toward the stationary structure 204, e.g., as indicated in FIG. 2B. The tab(s) 208 may be configured to compress and/or provide compliance to cushion lateral movement of the moveable platform 202 as the moveable platform 202 approaches the stationary structure 204. For example, the tab(s) 208 may be configured to engage with an inner surface of the stationary structure 204 when a lateral movement stroke of the moveable platform 202 reaches a stroke threshold. Furthermore, the tab(s) 208 may be configured to deflect towards the lens group when a lateral movement stroke of the moveable platform 202 exceeds the stroke threshold. For example, FIG. 2B shows a tab 208 in a deflected state 208′. In some examples, the stroke threshold may correspond to a functional range of lateral movement, e.g., a range of lateral movement stroke within which the lens group and/or the moveable platform 202 are shifted to provide optical image stabilization (OIS).

In some embodiments, the tab(s) 208 may serve as primary end stop portion(s) of the moveable platform 202, and the bumper arrangement 200 may include one or more secondary hard stop portions 210 of the moveable platform 202, e.g., as indicated in FIGS. 2A-2C. The moveable platform 202 may be structured such that a tab/primary end stop portion 208 protrudes (e.g., towards the stationary structure 204, away from the lens group, etc.) beyond a plane defined by a secondary hard stop portion 210 that is at the same side of the moveable platform 202. In some instances, the tab(s)/primary end stop portion(s) 208 may make contact with the stationary structure 204 before the secondary hard stop portion(s) make contact with the stationary structure 204. The tab(s)/primary end stop portion(s) 208 may cushion lateral movement of the moveable platform 202 when a lateral movement stroke of the moveable platform 202 exceeds a first stroke threshold. As indicated in FIG. 2C, contact between the secondary hard stop portion(s) 210 and the stationary structure 204 may stop lateral movement of the moveable platform 202. For example, the secondary hard stop portion(s) 210 may stop lateral movement of the moveable platform 202 when the lateral movement stroke of the moveable platform 202 reaches a second stroke threshold. In this example, the second stroke threshold may be greater than the first stroke threshold.

In some embodiments, the tab(s) 208 may be formed from the moveable platform 202. For example, the tab(s) 208 and the rest of the moveable platform 202 may be formed together (e.g., as a single component) via molding. In some embodiments, the tab(s) 208 and the moveable platform 202 may initially be separate components, and the tab(s) 208 may be insert molded with the moveable platform 202 to form a combined, insert molded component.

As indicated in FIG. 2A, one or more sides of the moveable platform 202 may include one or more tabs/primary end stop portions 208 and/or one or more secondary hard stop portions 210. In some non-limiting examples, a secondary hard stop portion 210 may be located between a pair of tabs/primary end stop portions 208. However, a side of the moveable platform 202 may include fewer or more tab(s)/primary end stop portion(s) 208 and/or secondary hard stop portion(s) 210. Furthermore, the tab(s)/primary end stop portion(s) 208 and/or the secondary hard stop portion(s) 210 may be located and/or oriented differently than indicated in FIGS. 2A-2C. As a non-limiting example, a side of the moveable platform 202 may have a first tab/primary end stop portion 208 that extends downward, and a second tab/primary end stop portion 208 that extends upward. A secondary hard stop portion 210 may be located between the first tab/primary end stop portion 208 and the second tab/primary end stop portion 208.

In some cases, the bumper arrangement 200 may reduce triboelectric static charge buildup by reducing an overall contact area between the moveable platform 202 and the stationary structure 204. As a non-limiting example, the contact area may be reduced when the first stroke threshold is reached or exceeded (e.g., such that the tab(s)/primary end stop portion(s) 208 make contact with the stationary structure 204) but the second stroke threshold is not reached (e.g., such that the secondary hard stop portion(s) 210 do not make contact with the stationary structure 204). In some embodiments, a coating (e.g., a conductive coating, an optically clear coating, etc.) (not shown) may be applied to at least a portion of the tab(s)/primary end stop portion(s) 208 and/or to at least a portion of the secondary end stop portion(s) 210. Selection of the material(s) of the coating may be based at least in part on their ability to reduce triboelectric static charge buildup resulting from contact between the coating and the stationary structure 204.

FIGS. 3A-3C illustrate views of yet another example bumper arrangement 300 a for cushioning lateral movement of a moveable platform of a camera. FIG. 3A shows a perspective view of the bumper arrangement 300 a. FIG. 3B shows a top view of the bumper arrangement 300 a. FIG. 3C shows a top view of an example alternative embodiment 300 c of the bumper arrangement.

In some embodiments, the camera may be similar in some respects to the camera 100 described above with reference to FIGS. 1A-1G. For example, the camera may include a lens group (e.g., lens 102 in FIG. 1A), a lens carrier (e.g., lens carrier 122 in FIG. 1A), an image sensor (e.g., image sensor 104 in FIG. 1C), an actuator (e.g., actuator 106 in FIG. 1A), a stationary structure 302 a, 302 c, and/or a moveable platform 304 a, 304 c (see FIGS. 3B-3C). The lens group may include one or more lens elements that define an optical axis. The image sensor may capture light that passes through the lens group. The actuator may be configured to move the lens group relative to the image sensor. Furthermore, the camera may include a suspension spring structure, such as the suspension spring structure described above with reference to FIGS. 1A-1G.

According to some embodiments, the stationary structure 302 a, 302 c may include a shield can that covers at least a portion of the internal component(s) of the camera. Furthermore, the moveable platform 304 a, 304 c may include a magnet holder that holds one or more magnets (e.g., magnet 124 in FIG. 1A) of the actuator. In other embodiments, the stationary structure 302 a, 302 c may include one or more components other than the shield can, and the moveable platform 304 a, 304 c may include one or more components other than the magnet holder.

In some embodiments, the moveable platform 304 a, 304 c may be coupled to the lens group. For instance, the moveable platform 304 a, 304 c may be coupled to the lens group such that the moveable platform 304 a, 304 c moves together (e.g., in lockstep) with the lens group, e.g., when the actuator moves the lens group relative to the image sensor. In some examples, the moveable platform 304 a, 304 c may be coupled to the lens group such that the moveable platform 304 a, 304 c and the lens group are moveable together in one or more directions orthogonal to the optical axis. In various embodiments, the moveable platform 304 a, 304 c may have multiple sides, e.g., four sides like the moveable platform 110 shown in FIG. 1B. The moveable platform 304 a, 304 c may encircle the lens carrier and/or the lens group in some embodiments. The moveable platform 304 a, 304 c may have fewer or more than four sides in some embodiments.

According to various embodiments, the bumper arrangement 300 a shown in FIGS. 3A-3B may include one or more tabs 306 a that protrude from the stationary structure 302 a, e.g., such that the tab(s) 306 a extend toward the moveable platform 304 a. The tab(s) 306 a may be configured to compress and/or provide compliance to cushion lateral movement of the moveable platform 304 a as the moveable platform 304 a approaches the stationary structure 302 a. For example, the tab(s) 306 a may be configured to engage with an outer surface of the moveable platform 304 a when a lateral movement stroke of the moveable platform 304 a reaches a stroke threshold. Furthermore, the tab(s) 306 a may be configured to deflect away from the lens group when a lateral movement stroke of the moveable platform 304 a exceeds the stroke threshold. In some examples, the stroke threshold may correspond to a functional range of lateral movement, e.g., a range of lateral movement stroke within which the lens group and/or the moveable platform 304 a are shifted to provide OIS.

In various embodiments, the tab(s) 306 a may be formed from the stationary structure 302 a. For example, the tab(s) 306 a may be defined from the stationary structure 302 a via laser ablating, stamping, punching, and/or otherwise removing material from the stationary structure 302 a.

One or more sides of the stationary structure 302 a may include one or more tabs 306 a. FIGS. 3A-3B show a side of the stationary structure 302 a having a single tab 306 a that located in a central portion of the side. The tab 306 a may include a root end 308 a (e.g., an end that is connected to the rest of the stationary structure 302 a) and a free end 310 a (e.g., an end that is distal to the root end 308 a). In various embodiments, a side of the stationary structure 302 a may include multiple tabs 306 a. Furthermore, the tab(s) 306 a may be located and/or oriented differently than indicated in FIGS. 3A-3B. As a non-limiting example, one or more sides of the stationary structure 302 a may include a first tab and a second tab. The respective free ends 310 a of the first tab and the second tab may be oriented in the same direction, or in different directions (e.g., in opposite directions).

In some non-limiting embodiments, a portion of the stationary structure 302 a may be laser ablated to a desired thickness to form a body of a tab 306 a, and a C-shaped (or U-shaped) pattern may be fully ablated (e.g., completely through the thickness of the stationary structure 302 a) to form outer edges of the tab 306 a, which may define a root end 308 a and a free end 310 a of the tab 306 a. According to some embodiments, the body of tab 306 a may have a tapered thickness. For example, the root end 308 a of the tab 306 a may be thicker than the free end 310 a of the tab 306 a. A gradient of thicknesses may exist between the root end 308 a and the free end 310 a. For example, the tab 306 a may gradually decrease in thickness from the root end 308 a to the free end 310 a, which may be achieved by applying laser ablation in a tapered manner in some embodiments.

According to various embodiments, the bumper arrangement 300 c shown in FIG. 3C may include one or more tabs 306 c defined by the stationary structure 302 c. In some embodiments, the tab(s) 306 c may not protrude toward the moveable platform 304 c, but may extend parallel to a plane defined by an outer surface of the moveable platform 304 c, e.g., as indicated in FIG. 3C. The bumper arrangement 300 c may include one or more protrusions 308 c attached to (and/or defined by) the moveable platform 304 c. The tab(s) 306 c may be configured to engage corresponding protrusion(s) 308 c and compress and/or provide compliance to cushion lateral movement of the moveable platform 304 c as the moveable platform 304 c approaches the stationary structure 302 c. For example, a tab 306 c may be configured to engage with a corresponding protrusion 308 c when a lateral movement stroke of the moveable platform 304 c reaches a stroke threshold. Furthermore, the tab 306 c may be configured to deflect away from the lens group when a lateral movement stroke of the moveable platform 304 c exceeds the stroke threshold. In some examples, the stroke threshold may correspond to a functional range of lateral movement, e.g., a range of lateral movement stroke within which the lens group and/or the moveable platform 304 c are shifted to provide OIS.

In various embodiments, the tab(s) 306 c may be formed from the stationary structure 302 c. For example, the tab(s) 306 c may be defined from the stationary structure 302 c via laser ablating, stamping, punching, and/or otherwise removing material from the stationary structure 302 c.

One or more sides of the stationary structure 302 c may include one or more tabs 306 c, and one or more corresponding protrusions 308 c may be attached to one or more sides of the moveable platform 304 c. FIG. 3C shows a side of the stationary structure 302 c having a single tab 306 c that located in a central portion of the side. In various embodiments, a side of the stationary structure 302 c may include multiple tabs 306 c. Furthermore, the tab(s) 306 c may be located and/or oriented differently than indicated in FIG. 3C. As a non-limiting example, one or more sides of the stationary structure 302 c may include a first tab and a second tab. The respective free ends of the first tab and the second tab may be oriented in the same direction, or in different directions (e.g., in opposite directions).

In some non-limiting embodiments, a portion of the stationary structure 302 c may be laser ablated to a desired thickness to form a body of a tab 306 c, and a C-shaped (or U-shaped) pattern may be fully ablated (e.g., completely through the thickness of the stationary structure 302 c) to form outer edges of the tab 306 c, which may define a root end and a free end of the tab 306 c. According to some embodiments, the body of tab 306 a may have a tapered thickness. For example, the root end of the tab may be thicker than the free end of the tab 306 c. A gradient of thicknesses may exist between the root end and the free end, e.g., as discussed above with reference to FIGS. 3A-3B. In some embodiments, the thickness(es) of the body of the tab 306 c may designed to account for the lateral movement stroke of the moveable platform 304 c. For example, laser ablation may be used to reduce the thickness of the stationary structure 302 c to form the body of the tab 306 c such that a maximum lateral movement stroke of the moveable platform 304 c is accounted for within the original thickness of the stationary structure 302 c. In this manner, a maximum deflection of the tab 306 c may not protrude beyond an outer surface of the stationary structure 302 c, e.g., as indicated by the deflected state 306 c′ of the tab 306 c shown in FIG. 3C.

It should be appreciated that device 400 is only one example of a portable multifunction device, and that device 400 may have more or fewer components than shown, may combine two or more components, or may have a different configuration or arrangement of the components. The various components shown in FIG. 4 may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

Memory 402 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 402 by other components of device 400, such as CPU 420 and the peripherals interface 418, may be controlled by memory controller 422.

Peripherals interface 418 can be used to couple input and output peripherals of the device to CPU 420 and memory 402. The one or more processors 420 run or execute various software programs and/or sets of instructions stored in memory 402 to perform various functions for device 400 and to process data.

In some embodiments, peripherals interface 418, CPU 420, and memory controller 422 may be implemented on a single chip, such as chip 404. In some other embodiments, they may be implemented on separate chips.

RF (radio frequency) circuitry 408 receives and sends RF signals, also called electromagnetic signals. RF circuitry 408 converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals.

Audio circuitry 410, speaker 411, and microphone 413 provide an audio interface between a user and device 400. Audio circuitry 410 receives audio data from peripherals interface 418, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 411. Speaker 411 converts the electrical signal to human-audible sound waves. Audio circuitry 410 also receives electrical signals converted by microphone 413 from sound waves. Audio circuitry 410 converts the electrical signal to audio data and transmits the audio data to peripherals interface 418 for processing. Audio data may be retrieved from and/or transmitted to memory 402 and/or RF circuitry 408 by peripherals interface 418. In some embodiments, audio circuitry 410 also includes a headset jack (e.g., 512, FIG. 5). The headset jack provides an interface between audio circuitry 410 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

I/O subsystem 406 couples input/output peripherals on device 400, such as touch screen 412 and other input control devices 416, to peripherals interface 418. I/O subsystem 406 may include display controller 456 and one or more input controllers 460 for other input or control devices. The one or more input controllers 460 receive/send electrical signals from/to other input or control devices 416. The other input control devices 416 may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 460 may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 508, FIG. 5) may include an up/down button for volume control of speaker 411 and/or microphone 413. The one or more buttons may include a push button (e.g., 506, FIG. 5).

Touch-sensitive display 412 provides an input interface and an output interface between the device and a user. Display controller 456 receives and/or sends electrical signals from/to touch screen 412. Touch screen 412 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects.

Touch screen 412 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 412 and display controller 456 (along with any associated modules and/or sets of instructions in memory 402) detect contact (and any movement or breaking of the contact) on touch screen 412 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch screen 412. In an example embodiment, a point of contact between touch screen 412 and the user corresponds to a finger of the user.

Touch screen 412 may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen 412 and display controller 456 may detect contact and any movement or breaking thereof using any of a variety of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 412. In an example embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif.

Touch screen 412 may have a video resolution in excess of 800 dpi. In some embodiments, the touch screen has a video resolution of approximately 860 dpi. The user may make contact with touch screen 412 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 400 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from touch screen 412 or an extension of the touch-sensitive surface formed by the touch screen.

Device 400 also includes power system 462 for powering the various components. Power system 462 may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 400 may also include one or more optical sensors or cameras 464. FIG. 4 shows an optical sensor 464 coupled to optical sensor controller 458 in I/O subsystem 406. Optical sensor 464 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 464 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module 443 (also called a camera module), optical sensor 464 may capture still images or video. In some embodiments, an optical sensor 464 is located on the back of device 400, opposite touch screen display 412 on the front of the device, so that the touch screen display 412 may be used as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display.

Device 400 may also include one or more proximity sensors 466. FIG. 4 shows proximity sensor 466 coupled to peripherals interface 418. Alternately, proximity sensor 466 may be coupled to input controller 460 in I/O subsystem 406. In some embodiments, the proximity sensor 466 turns off and disables touch screen 412 when the multifunction device 400 is placed near the user's ear (e.g., when the user is making a phone call).

Device 400 includes one or more orientation sensors 468. In some embodiments, the one or more orientation sensors 468 include one or more accelerometers (e.g., one or more linear accelerometers and/or one or more rotational accelerometers). In some embodiments, the one or more orientation sensors 468 include one or more gyroscopes. In some embodiments, the one or more orientation sensors 468 include one or more magnetometers. In some embodiments, the one or more orientation sensors 468 include one or more of global positioning system (GPS), Global Navigation Satellite System (GLONASS), and/or other global navigation system receivers. The GPS, GLONASS, and/or other global navigation system receivers may be used for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 400. In some embodiments, the one or more orientation sensors 468 include any combination of orientation/rotation sensors. FIG. 4 shows the one or more orientation sensors 468 coupled to peripherals interface 418. Alternately, the one or more orientation sensors 468 may be coupled to an input controller 460 in I/O subsystem 406. In some embodiments, information is displayed on the touch screen display 412 in a portrait view or a landscape view based on an analysis of data received from the one or more orientation sensors 468.

In some embodiments, the software components stored in memory 402 include operating system 426, communication module (or set of instructions) 428, contact/motion module (or set of instructions) 430, graphics module (or set of instructions) 432, text input module (or set of instructions) 434, Global Positioning System (GPS) module (or set of instructions) 435, arbiter module 458 and applications (or sets of instructions) 436. Furthermore, in some embodiments memory 402 stores device/global internal state 457. Device/global internal state 457 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display 412; sensor state, including information obtained from the device's various sensors and input control devices 416; and location information concerning the device's location and/or attitude.

Operating system 426 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 428 facilitates communication with other devices over one or more external ports 424 and also includes various software components for handling data received by RF circuitry 408 and/or external port 424. External port 424 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector.

Contact/motion module 430 may detect contact with touch screen 412 (in conjunction with display controller 456) and other touch sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 430 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 430 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 430 and display controller 456 detect contact on a touchpad.

Contact/motion module 430 may detect a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns. Thus, a gesture may be detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event.

Graphics module 432 includes various known software components for rendering and displaying graphics on touch screen 412 or other display, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like.

In some embodiments, graphics module 432 stores data representing graphics to be used. Each graphic may be assigned a corresponding code. Graphics module 432 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 456.

Text input module 434, which may be a component of graphics module 432, provides soft keyboards for entering text in various applications (e.g., contacts 437, e-mail 440, IM 441, browser 447, and any other application that needs text input).

GPS module 435 determines the location of the device and provides this information for use in various applications (e.g., to telephone 438 for use in location-based dialing, to camera 443 as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).
